Y, t l 1, f j 'Referringfto the drawings formore de-' f tailed description thereof, .the numeral 7 f indicatesa tubular member circular 'v at f its l flower portion for 'Haring outwardlyy in' its upper'y portion and f terminating in four lstraight upper end lportions 8, 9, 10 and 11,

which are atv right" angles to each othersv A These upper vend portions are circularly bent to form tubes through which are respectively passed pinsf12,'13,r14, and Y1'5.

The ends ofthe straight vtubular members 18, 9, 10 l'and 11 are cutaway at their ends Vso that the ends of the pins- 12Y to 15 .inelusive project therefrom. Plates 17, l18,y

19 and 20 are respectively hingedlysecured to the upper tubularend portions 8, 9, 10 and 11 by Vhaving llowerend portions thereof bent' around` the end portions ofthe'pins 12, V13, 14` and 15 which'protrude frommthe tubular portions 8, 9, land 11.' l

These plates are adapted to be swung inwardly to the` position -shown inFigure 1,

This invention relates'toA closures for the pyramid@ The adjacent sides of the'adja-v cent plates, `being bevelled, contact 'with'k eachother vso that close joints vare madef portions ofthe plates '17, "18,7

-The plates'are alsofcapable, bymeansfof i their hingedconnection, ofbeing swung outwardly into the position shownin Figure 5.4 Extensible'means are provided to fillin the gaps'which "exist vbetween 'the vplates when Ythejlatter arev in the ope/n?

' The tops of the Plates *17' to` 20 inclusive i have extensionsof reduced widthlwhich ex"- tensionsare respectively numbered 52, 53, '54j` i and l55. @These extensions! are bentv at an'V anglel tojthe plates so that'when the 'latterv extensions are vertical'.

are 'closedfinto "afpyramidall ,formation-S the' i i A' The/cover is provided to close the topiof i tlie truncated pyramid, such cover beingY vdesignated by thei-numeral?, which has' a recess 58 in its'bvo'ttorn.V This recess encloses, I' I sel I the extensions 52 fto 55 inclusive and holds the plates 17 vto l2() inclusive, together. The cover 57 is provided with a hinge 59, Vone leaf of which is secured to the plate 17,

while the othery leaf' is securedtol the top-v of the recess by means of screws 60.

In order to hold the cover securely 'around the extensions of theplates a screw 61, shown in Figure 4l, passes through that side of thecover157 which .is opposite thepintle of thehinge 59, into the recess 58 and threadedly engages the cover.'Y The vscrew also passes through an aperture 62 in the exten s ioii 54: when the plates are in :closed formation, thus.securely holding the cover in an encircling position on the extensions of the plates, since the screw is provided with a head63 which abuts against the outer surface r of the cover 57. The screw 6l is also provided with yan end member 64, so that the screw connot be lost from the cover.

vlhen it is desiredrto open the device in order to forni a funnel, the screw 6l is turned until the end member 64 is with drawn from the extension `54h` The cover 57 is thenV pushed upwardly and backwardly;"this motion ofthe, cover isV effective in opening the plates and the hinges into the shape of a funnel.

The device described' and shown may be secured to a tube existing on a radiator or to the end of any other tioe or pipe by a set screw 65, passing transversely through one side'of the tubular member 7. The set screw 65 has a pointed .end 66 which may engage the tube or pipe to which the device 4of my a invention is tobe secured.
